Why does O2 have no plans to support Wifi calling? Surely O2 wants to provide its customers with the most update technology? Surely this would enrich our devices and make our experience much better?
Although no network offers everything you are behind Three in your offers of Data, EE in terms of speed please don't fall behind in user features that are available with the phone.
Wifi calling is nothing to do with ios 10.3 and o2, as it has been available since ios 8 from memory and o2 also do not support volte . All these are business decisions o2 take many threads about some of this .
